OPERATION GUIDE

This kit comes with a training board version and Windows version of the sample program. These can be used to carry out tests of the following 3 communication functions. 1. Cyclic data transmission between training boards 2. Ping pong data transmission between training boards 3. Ping pong data transmission between training board and PC To start up the sample program, follow the procedures in the “Explanation of the Training Board Version of the Sample Program” and “Explanation of the Windows Version of the Sample Program” below.

The sample program will not create a link unless the User ID, Group ID, Equipment ID, and communication channel of both units are the same. By resetting the MU-1 units on the training board and RS232C interface board, you can easily carry out tests using the default link parameters.

Preparation 1. Mount the MU-1 on the RS232C interface board, and using the RS232C straight cable provided, connect it to

the COM port of the PC. 2. Mount the MU-1 on the training board, and set the operation mode with the Mode DIP switch (SW2). 3. Turn off the power switches of the RS232C interface board and training board, and connect the power wires to

the power terminals.

How to start up 1. Turn on the power while pressing the initialize switch on the RS232C interface board. 2. Turn on the power while pressing the initialize switch on the training board. 3. Turn off all power, and after a short time (about 3 seconds), turn on the power again. 4. The link parameters are now set and testing is possible.

Parameter values after initializing 1. Cyclic data transmission between training boards, and ping pong data transmission between training boards Channel = Lowest channel, User ID = 0000, Group ID = 00 Equipment ID = 01, Destination ID = 01 * The equipment operates when the Equipment ID and the Destination ID of both units is 01. 2. Ping pong data transmission between training board and PC Channel = Lowest channel, User ID = 0000, Group ID = 00 Equipment ID is set automatically to 02 or 03 by DIP SW4. Destination ID is set automatically to 02 or 03 by DIP SW4. * Specify the equipment number with Mode DIP SW4. Off: Equipment ID = 02, Destination ID = 03 On: Equipment ID = 03, Destination ID = 02 3. The UART (or RS232C) communication parameters of the MU-1 are as follows. Bit rate = 19,200 bps, data length = 8 bits, stop bit = 1, parity bit = none

Chapter 2 The Sample Program

2.1 Easy Startup of the Sample Program


OPERATION GUIDE

2.2.1 The Program

The PIC microcomputer on the training board contains a program that performs the following communication functions. 1. Cyclic data transmission between training boards 2. Ping pong data transmission between training boards 3. Ping pong data transmission between training board and PC 4. Direct control of the MU-1 on the training board In order to use the various functions, it is first necessary to set the mode of the training boards to the master station and/or target station. The mode is activated by making the setting with the Mode DIP switch (SW2), then turning on the power. * Modes 0 to 5 in the following explanation indicate the processing routines of the program.

2.2.2 Functions 1. Cyclic data transmission between training boards The master station training board repeatedly transmits tact switch data (SW4..12). When the target station training board receives the data, the LEDs corresponding to the tact switch data come on. If the received data is interrupted for longer than 100 ms, all LEDs go off.

Mode 1: Master station training board settings Mode DIP switches: 1 = On 2 = Off 3 = Off 4 = N/A Mode 2: Target station training board settings Mode DIP switches: 1 = Off 2 = On 3 = Off 4 = N/A * N/A: This switch has no effect whether On or Off.

2. Ping pong data transmission between training boards Using the transceiver function of the MU-1, both the training boards transmit tact switch data. The received data is displayed on the LEDs. Both devices act as master station and target station. If the received data is interrupted for longer than 200 ms, all LEDs go off.

Mode 3: Training board 1 settings Mode DIP switches: 1 = On 2 = On 3 = Off 4 = N/A Mode 4: Training board 2 settings Mode DIP switches: 1 = Off 2 = Off 3 = On 4 = N/A

3. Ping pong data transmission between training board and PC Using the transceiver function of the MU-1, data is transmitted between the master station controlled by the Windows version of the sample program on the PC, and the target station training boards. The tact switch data of the training board is displayed by the receiving LEDs of the Windows version of the sample program, while the data transmitted by the program is displayed by the LEDs of the training board. The communication method is the polling method in which the target station training board transmits data in response to a query from the master station (PC). If the received data is interrupted for longer than 2,500 ms, all LEDs go off. For this kind of communication, use 2 training boards. (It is possible with just 1 board.)

Mode 5: Target station training board 1 settings Mode DIP switches: 1 = On 2 = Off 3 = On 4 = Off Mode 5: Target station training board 2 settings Mode DIP switches: 1 = On 2 = Off 3 = On 4 = On

* Specify the equipment number with Mode DIP SW4. Off = Target station training board 1, with Equipment ID of 02. On = Target station training board 2, with Equipment ID of 03. The Equipment ID of the MU-1 connected to the PC is 01 when it is reset. Do not change it.

2.2 Explanation of the Training Board Version of the Sample Program


OPERATION GUIDE 4. Direct control of the MU-1 on the training board This function provides direct control of the MU-1 mounted on the training board, from an RS232C communication program such as the MU-1 Evaluation Program, HyperTerminal or the like. In this way you can set a variety of link parameters and test them. In order to achieve this function, make the following settings. • Mount the UART adapter on the RS232C interface board. • Connect the training board and the UART adapter with the connection cable provided. • Connect the RS232C interface board and the PC with the RS232C straight cable provided. • Mode 0: Mode DIP switch settings 1 = Off 2 = Off 3 = Off 4 = N/A

2.3.1 The program

Using the Application Design Kit transmission test sample program included in the MU-1 Evaluation Program (MU1-ESP) (also called the Windows version of the sample program), you can perform communication with the training board version of the sample program. The sample program uses the polling method for communication. Refer to the MU1-ESP Operation Guide for details.

2.3.2 How to use the program The transmission test window for the Application Design Kit is a sample program for performing communication between 2 training boards. In response to a query from the PC to the training board (a command to turn on its LEDs), the training board returns its own data. 1. Connect the RS232C interface board mounted with the MU-1 to the COM port of the PC. Use the RS232C

straight cable provided.

2. Turn on the power while pressing the initialize switch on the RS232C interface board. Then turn off the power, and turn it on again. The RS232C parameters and link related IDs and so on are set to the default values.

3. Start up the program by clicking “MU1_ESP.exe” in the “...¥Desktop¥Circuit Design¥MU1_EP” folder. When the program starts up, a dialog explaining how to use the program appears. Message: “Please select the model first, then open the COM port.” After checking the settings, click the “OK” button. The main program starts up.

4. Select an MU-1 from the MU-1 selection box.

5. Click the COM port button and open the port. The operation screen appears. Follow the procedure in the explanatory screen. * The default values for the MU-1 communication parameters are as follows. 19,200 bps, 8-bit, 1 stop bit, no parity If the communication parameters are changed by a command, set all the communication parameters to the same setting with “COM port” in the Setting menu.

2.3 Explanation of the Windows Version of the Sample Program


OPERATION GUIDE

2.3.3 Explanation of the transmission test window With this sample you can carry out communication tests with the training board included in the Application Design Kit. Note that this only works with the training board. It does not support the relay function. In other words, communication is based on the content of the Destination ID. In this transmission test, data set with the LED data setting button for transmission (1 byte) is sent to the training board, and the switch data and VR1 and 2 data from the training board is read and displayed on the screen. You can connect a maximum of 2 training boards, and the Windows version of the sample program alternately reads and displays their data. [5] and [10] in the figure is the data to be displayed by the LEDs on the training board, and each represents 1 byte of data. When the training board receives this data, it returns the switch data and VR1 and 2 data.

OPERATION GUIDE

Here we explain the items necessary for developing a user program, taking examples from the training board sample program and the Windows version of the sample program included in the MU-1 Evaluation Program. We recommend that you use the sample program to evaluate the training board before creating your user program.

3.1.1 The emulator

The training board is mounted with the Microchip Technology PIC16LF877-20/P. In order to develop a program using the training board, an ICE is necessary. For details, refer to the Microchip Technology homepage. When connecting the ICE, if necessary disconnect the clock of the training board with CN5.

3.1.2 Components and ports available to the user

You can use the following ports and components with the training board, however, be sure that you have a full understanding of the circuit diagram before creating your program. RB0..7 Output ports: 8 (with output monitor LED2..9) RD0..7 Input ports: 8 (joint use tact switch SW4..12 / DIP switch SW11) RA4 Input ports: 1 (tact switch SW3) AN0..1 AD conversion ports: 2 (variable resistors VR1, VR2) AN2..4 AD conversion ports: 3 (CN7) RE0..2 Input ports: 3 (DIP switch SW2) RC3 Input ports: 1 (DIP switch SW2) CN6, CN7, CN9 The through holes for these connectors are available to the user, however since a variety of components

are connected to these signal lines, care is required when using them.

3.1.4 Direct control of the MU-1 on the training board

In order to provide the MU-1 mounted on the training board with a direct control function from an RS232C communication program (such as the MU-1 Evaluation Program, HyperTerminal or the like), connect the RS232C interface board and training board with the UART adapter and connection cable provided. To achieve this function, it is necessary to disconnect the MU-1 terminal function from the PIC microcomputer port and replace it directly with the CN2 connector. In other words, in order to prevent electrical conflicts among the signals, it is necessary to look at the status of the ports available to the user such as the SW2 (DIP switch) port, and make a program in which the PIC microcomputer RC0, 1, 2, 6 and 7 ports are set as input ports.

Caution: With HyperTerminal, the DTR line is always fixed at High Level and cannot be controlled.


OPERATION GUIDE

3.2.1 The source code

The source code of the sample program can be found as a text file with the filename “MU-1_TB.txt” on the setup disk. This sample program is intended as the minimum code required for understanding how to control the MU-1, and it is not optimized for use. In an actual program, it is necessary to change the channel and Destination ID, however for this kind of control, command processing rules must be followed. For details, refer to “How to Develop an Application Using the MU-1” in the MU-1 Operation Guide.

3.2.2 Communication operation details

A flow chart for the sample program for the training board is shown below. The program determines the status of SW2 and branches to the appropriate mode processing routine. Each mode has its own loop. The processes within each mode are as shown in flow chart 2. The Equipment ID The Equipment ID of the MU-1 on the RS232C interface board connected to the PC is 01 when the MU-1 is operating. Do not change it. In addition, the Equipment ID of training board 1 is 02, while the Equipment ID of training board 2 is 03.

OPERATION GUIDE

3.3.1 Settings

Here we explain how the function explained in “3. Ping pong data transmission between training board and PC” for the training board version of the sample program is implemented in the Windows version of the sample program. The Windows version of the sample program is included in the MU-1 Evaluation Program. The training board settings are as follows.

Target station training board 1 settings Mode DIP switches: 1 = On 2 = Off 3 = On 4 = Off Target station training board 2 settings Mode DIP switches: 1 = On 2 = Off 3 = On 4 = On

* Specify the equipment number with Mode DIP SW4. Off = Target station training board 1, with Equipment ID of 02. On = Target station training board 2, with Equipment ID of 03. * The Equipment ID of the MU-1 connected to the PC is 01. Do not change it.

3.3.2 Communication operation details

1. To make the LEDs on the training board light up from the Windows version of the sample program, specify the

Equipment ID of the training board MU-1, and transmit 1 byte of data. In other words, having decided the destination training board, specify the Equipment ID of the target station as the Destination ID.

To transmit to training board 1, specify the following ‘@DI02’CRLF Then after acquiring the LED data to transmit, transmit the following data. ‘@DT01’ + LED data + CRLF

In this case the commands are issued continuously.

* For detailed information about the processes for continuously issuing commands and the responses, refer to “How to Develop a Program for a System Using the MU-1” in the MU-1 Operation Guide.

2. The training board that receives the 1-byte data sends the 5-bytes consisting of the control code, board number,

SW data and VR1 and 2 data to the on-board MU1. ‘@DT05’ + control code + board number + SW data + VR1 data + VR2 data + CRLF

3. The Windows version of the sample program identifies the control code in the receive response received, and

performs the corresponding process. ‘*DT05’ + control code + board number + SW data + VR1 data + VR2 data + CRLF

The only operations of the Windows version of the sample program for 2 training boards are specifying the destination training board, and identifying the board number in the received data and switching between boards.

OPERATION GUIDE

Cautions • As the radio module communicates using electronic radio waves, there may be cases where transmission is

temporarily cut off due to the surrounding environment and method of usage. The manufacturer is exempt from all responsibility relating to resulting harm to personnel or equipment and other secondary damage.

• Do not use the equipment within the vicinity of devices that may malfunction as a result of electronic radio waves from the radio module.

• The manufacturer is exempt from all responsibility relating to secondary damage resulting from the operation, performance and reliability of equipment connected to the radio module.

• Communication performance will be affected by the surrounding environment, so communication tests should be carried out before actual use.

• Ensure that the power supply for the radio module is within the specified rating. Short circuits and reverse connections may result in overheating and damage and must be avoided at all costs.

• Ensure that the power supply has been switched off before attempting any wiring work. • The case is connected to the GND terminal of the internal circuit, so do not make contact between the '+' side of

the power supply terminal and the case. • When batteries are used as the power source, avoid short circuits, recharging, dismantling, and pressure. Failure

to observe this caution may result in the outbreak of fire, overheating and damage to the equipment. Remove the batteries when the equipment is not to be used for a long period of time. Failure to observe this caution may result in battery leaks and damage to the equipment.

• Do not use this equipment in vehicles with the windows closed, in locations where it is subject to direct sunlight, or in locations with extremely high humidity.

• The radio module is neither waterproof nor splash proof. Ensure that it is not splashed with dirt or water. Do not use the equipment if water or other foreign matter has entered the case.

• Do not drop the radio module or otherwise subject it to strong shocks. • Do not subject the equipment to condensation (including moving it from cold locations to locations with a

significant increase in temperature.) • Do not use the equipment in locations where it is likely to be affected by acid, alkalis, organic agents or corrosive

gas. • Do not bend or break the antenna. Metallic objects placed in the vicinity of the antenna will have a great effect on

communication performance. As far as possible, ensure that the equipment is placed well away from metallic objects.

• The GND for the radio module will also affect communication performance. If possible, ensure that the case GND and the circuit GND are connected to a large GND pattern.

Warnings • Do not take apart or modify the equipment. • Do not remove the product label (the label attached to the upper surface of the module). • Using a module from which the label has been removed is prohibited.
